Shift L2556. Start at 202:12:00 GMT = 08:00am 21 Jul EDT End 10:00am 21 Jul SOT Lead DAS (Times will be given in GMT on day 202.) PLAN ---- Continue running load JUL1706B. Finish the egress cti run and do obsid 6835, an ACIS-S observation of the quasar lens system Q2237+030 to determine the X-ray vs optical emitting region size via microlensing. Then do obsid 6718, another segment of the long ACIS-S observation of Kepler's supernova remnant to map Fe-K line and continuua. Next Comms: 202:1920 to 2020 203:0215 to 0315 203:1245 to 1445 203:2105 to 2305 204:0345 to 0445 204:1140 to 1240 204:1850 to 1950 205:0150 to 0250 205:1325 to 1525 Orbital events: 2006:202:03:18:21.133 960 EPERIGEE ORBIT PERIGEE 2006:203:11:01:51.191 961 EAPOGEE ORBIT APOGEE 2006:204:18:45:32.515 961 EPERIGEE ORBIT PERIGEE 2006:206:02:29:39.350 962 EAPOGEE ORBIT APOGEE 2006:207:10:12:55.757 962 EPERIGEE ORBIT PERIGEE 2006:208:17:57:24.708 963 EAPOGEE ORBIT APOGEE 2006:210:01:40:41.390 963 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 202:11:39, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 359.998 deg Dec = 0.002 deg ROLL = 113.447 deg Format = 2 OBSID = 58868 acis CTI SIM FA = -467 SIM TSC = -99615 (HRC-S) DITHER = ENAB HETG = OUT (79.09 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = SMAL E150 = 7.6 E300 = 0.2 E1300 = 0.3 LT 20.0 (RADMON P4GM = 0.0 LT 300.

EPH temp: 107.86 degF EPH 27V: 26.84 NOTES/ISSUES/PROBLEMS The EPHIN 27v is reading 26.84 at LOS, despite the temperature being 107.86 for at least the 1 hour of the pass duration. We had been at about 118 degrees pitch for about 17 hours as of LOS. From the 9am status meeting: Two supports over the past day, no issues. First segment of the JUL2406B loads was uplinked, on-board loads are good until 206:10:20. A 4--12 day ToO was accepted and will be scheduled the week of JUL2406. The entire week will be replanned. Look for products and for a load review later today. SUBSEQUENT TO THE MEETING THE ToO WAS WITHDRAWN, NO CHANGES WILL BE MADE. Yesterday's FD CCB approved the PLINE monitor patches. We anticipate CAP reviews next Monday to prepare for uplinking the patches.
